Recommendations for cable management
Follow these suggestions for better cable organization and management:
• Plan cable management before installing the MP Router to ensure adequate rack space.
• Leave at least one meter of slack for each port cable. This provides room to remove and replace
the MP Router, allows for inadvertent rack movement, and helps prevent the cables from being
bent to less than the minimum bend radius.
• Label the fiber optic cables and record the devices to which they are connected for easier
maintenance.
• Keep LEDs visible by routing port cables and other cables away from the LEDs.
• Do not use tie wraps on fiber optic cables. Tie wraps can damage the optic fibers.
CAUTION: A fiber-optic cable should not be bent to a radius less than 2 inches under full tensile
load and 1.2 inches with no tensile load.
Installing SFP transceivers
Use the following procedure to connect the SFPs and cables to MP Router ports as required.
NOTE: The ports and cables used in trunking groups must meet specific requirements. For a list of
these requirements, see the
HP StorageWorks XPath OS 7.4.x administrator guide.
1. Identify the ports to connect to the fabric.
2. Remove the shipping plug from the appropriate ports.
3. Position the SFP so that the key (the tab near the cable-end of the SFP) is on top.
NOTE: The SFP is keyed so that it can be inserted only with the correct orientation into the port. If
the SFP does not slide in easily, check the orientation
4. Insert the SFP into the port until it is firmly seated and the latching mechanism clicks.
